The Sauerland [ hear (help·info)] is a rural, hilly area spreading across most of the south-eastern part of North Rhine-Westphalia, in parts heavily forested and, apart from the major valleys, sparsely inhabited. For these reasons, it has been chosen as the first place in Germany to reintroduce the Wisent (or European bison).
The Sauerland is the largest tourist region in North Rhine-Westphalia, in particular for mountain biking & cycling, water sports and scenic recreation. The town and Skiliftkarussell of Winterberg in the Hochsauerlandkreis is a major winter sport resort.
The name Sauerland is first mentioned as Suderland in an official document from 1266. After 1400 the letter 'd' started to disappear. Therefore Sauerland = southern country is the most convincing meaning, opposed to the theory that Sauer is from the German word sauer meaning sour (poor "sour" soil). Linguistically, "suder-“ is similar to the Old Saxon sûðar (southbound).
Before 1800 the western part of the Sauerland was part of the County of the Mark based in Altena; the eastern part adhered to the County of Arnsberg, later became known as the Duchy of Westphalia and was owned by the Archbishops and Electorate of Cologne. The Duchy of Limburg covered a very small area in the lower Lenne river valley. After the Napoleonic Wars the area became part of Prussia and was integrated into the new province of Westphalia. After World War II Westphalia was merged with the new federal state of North Rhine-Westphalia. Today, the Sauerland belongs to the districts Märkischer Kreis, Olpe and Hochsauerland. The western part of the Hessian district Waldeck-Frankenberg is also attributed to the Sauerland because of its geomorphological as well as sociocultural similarity and the stark contrast to the rest of the adjoining Hessian landscape.
To the west the hills continue into the Bergisches Land, to the south into the Siegerland, and to the north-east into the Teutoburg Forest. The major rivers of the Sauerland are the Ruhr and the Lenne. Several artificial lakes were created on the smaller rivers by building dams to store water for the nearby Ruhr area, the biggest reservoirs being the Möhne and Bigge. Although the highest elevation of the Sauerland is the Langenberg (843 m) near Olsberg, the much more renowned summit, which is well known for the nearby skiing facilities, its weather station and observation tower, is the slightly lower Kahler Asten (842 m) near Winterberg. Both Langenberg and Kahler Asten are peaks in the Rothaargebirge mountains.
Dams and reservoirs (lakes) 
The Sauerland has six reservoir lakes.
The Sauerland is part of the Rhine Massif (Rheinisches Schiefergebirge) including 'Bergisches Land', Westerwald, Siegerland, and, separated by the Rhine valley, the Eifel, Hohes Venn and Hunsrück. The Rheinisches Schiefergebirge was subjected to folding and faulting in the Variscan orogeny in Carboniferous times and eroded to a peneplain in the Permian. The tectonic uplift to the present-day low mountain range began approximately 500,000 years ago and is still going on.
Most of the Sauerland rock originates from a Middle and Upper Devonian marginal shallow sea; thus slates, sandstones and greywackes are the most abundant rock types. In some areas limestones from an ancient reef fringe prevail and are karstified. The Sauerland has several caves, especially in the northern part, the biggest caves being in Attendorn and Balve. In some areas of the Sauerland the occurrence of lead-zinc-silver-ores lead to the development of a considerable mining industry, the center of which was the town of Meggen. Mining in this area lasted until the late second half of the 20th century, today there is no active mining in the Sauerland. The sandstones, greywackes and quartzites of the Sauerland as well as, to a minor extent, the limestones are still exploited in numerous quarries.
Towns and municipalities 
Parts of the Sauerland, especially the major valleys in the northwest, represent an old industrial region. The availability of iron ore and the abundance of wood and water allowed iron production long before the Ruhr area industrialisation and the mining of its coal took place. Today there are only a few remains of this early heavy industry; wire production is still important in Altena and a number of small factories still occupy the old industrial areas. Warsteiner is Germany's largest privately owned brewery.
Today the Sauerland is a popular tourist area, attracting many visitors from the Ruhr Area and relatively close Netherlands. The forests and picturesque small towns are attractive for hikers and outdoor sports. There are more than 30,000 km of tagged hiking trails in Sauerland region maintained by Sauerland hiking association (SGV). Some of the towns have the title Bad (Spa) because of their good air quality and stimulating climate. Winter sports are popular in the Sauerland. The bob sleigh track in Winterberg is widely known in Germany, as well as the ski jumping in Willingen. Sauerland also has a successful theme park called Fort Fun.
The Sauerland can be reached by car or train. The drive either via the BAB 4 from Cologne or via the BAB 45 and BAB 46 from Dortmund, takes about one hour; from Kassel or Frankfurt-Rhine-Main (via the Sauerlandlinie) the journey takes about two hours. Iserohn station has regular regional train services. The closest commercial airport is Dortmund Airport.
